Question

USE the function below to find f(3) f(x)=1/34x

Answer 1

Below

Explanation:

f(x) = 1/3 * 4^x to find f(3) put '3' where 'x' is and compute

f(3) = 1/3 * 4^3

f(3) = 1/3 * 64 = 64/3

Answer 2

Option:-

• 
  `\large \boxed{ \tt \green {b) f(3) = (64)/(3) }}`

`\:`

Given:-

• 
  `\tt \: f( x ) = (1)/(3) 4^x`

• 
  `\tt \: f( 3 ) \: = ?`

`\:`

Solution:-

• 
  `\tt \: f(x) = (1)/(3) * {4}^(x)`

put the value of x = 3 :

• 
  `\tt \: f(3) = (1)/(3) * {4}^(3)`

`\:`

• 
  `\tt \: f(3) = (1)/(3) * 64`

`\:`

• 
  `\boxed{ \tt \purple{ f(3) = (64)/(3) }}`

`\:`

hope it helps! :)
